Finally, you can use git am to apply your patch as a commit: it allows you to sign off an applied patch.
This can be useful for later reference.

See an example in this article:

In your git log, you’ll find that the commit messages contain a “Signed-off-by” tag. This tag will be read by Github and others to provide useful info about how the commit ended up in the code.

This guide provides a basic overview for applying a patch to a program or file.

The command used for applying patches is the patch command but in order to apply a patch the diff command also needs to be used to supply the differences that need to be patched.

Why Would You Create a Patch

Imagine you had an HTML file as follows:

How To Use Patch File

The above source, when loaded into a web browser, will show the words 'Welcome to MySite'.

It is common when programming for there to be multiple versions of the same file. For instance there would be one version which is the current live version, there would be another version on the development branch which may contain multiple changes, finally, there might be another version on a release branch.

The release branch would be the version used by real users (i.e in this case visitors to the MySite website). Let us say that MySite is at version 1.0. After a development phase, you will create a release branch which would be in this case 1.1. The development branch will be ahead of the release branch because it may contain changes that aren't due for release in version 1,2 but will be for version 1.1.

Imagine there was a bug whereby MySite should be called YourSite. You could go to each branch in turn and make changes to the live version, development version and release version of you could make the change as a hotfix in live and then apply the patch to the development and release branches.

A Worked Example

Create a file called myfile.html with the following code in it:

Create another file called myfile_v2.html with the following code in it:

The first file is the original web page with the heading 'Welcome to MySite'. The second file is the same as the first file except MyFile is renamed to YourFile in the text.

How to Create the Diff File

In order to create a patch, we need to work out the differences between myfile.html and myfile_v2.html.

We can do this with the diff command as follows:

You can open the myfile.patch file in the nano editor as follows in order to view it:

Lines that are unchanged are shown in blue. Lines that have been removed are shown in red and lines that have been added are shown in green.

How to Apply the Patch Using the Patch Command

To apply the patch to myfile.html use the following command:

This will apply the changes created using the diff command to the original file myfile.html.

IntroductionSplitting, trimming and joining video files can be done losslessly and very fast if you use good tools. I hear you ask. Well, one of my friends just tried using Windows Movie Maker to remove ads from one of his TV recordings: after setting up the editing operations, it took another 30 minutes to process the file.

There are far better tools than the patch command for creating patches and ensuring good source control.

How To Apply Patch File

There is a reason that so many development projects use GIT for source control. GIT makes it easy to create a consistent branching strategy.
